You have purchased Auto Meter’s Clean Power System
designed to supply clean voltage regulated power for
charging and maintaining battery state of charge during ash
reprogramming, performing complex vehicle maintenance, and vehicle
show room demonstrations. The system will deliver a regulated voltage
up to its rated current output. The Clean Power System uses coaxial
leads that has a separate conductor to measures and display the voltage
that is at the battery terminals.

CARE AND MAINTENANCE
B AT T ERY
Both jaws of each clamp
must rmly engage the
battery terminal. The
copper jaw contains the
smaller gauge wire that
reads the voltage and
the silver jaw contains
the larger conducting
wire that draws the
load in each test. Jaw
insulation is necessary
for accurate readings.
Damaged clamps or
loose wires will affect the
readings. Keep clamps
clean and in good repair.
CHECK OFTEN FOR LOOSE JAWS
OR DAMAGED INTERNAL PLASTIC
SHOULDER INSULATORS
BATTERY LEAD & CLAMP REPLACEMENT
PROCEDURE
Unplug small voltmeter lead connector.
Using a screwdriver, loosen the positive and the negative set
screws in the terminal block.
Remove leads.
Install the new leads into the terminal block making sure the red
clamp lead is in the terminal block marked (+), and the black
clamp lead is in the terminal block marked (-).
Orientate the leads in the terminal block so that the smaller
voltmeter leads are on top.
Firmly tighten the set screw in the terminal block.
Plug in voltmeter connector.

Carefully read all operating instructions before
using the Clean Power System.
Wear eye protection when working around
batteries.
The Clean Power System is equipped with a
power cord. Never use an extension cord that is
more than 50ft and it must not be smaller than
12 gauge. Make sure the extension cord and
receptacle are properly grounded.
Be sure to switch the power off before removing
the clamps to prevent arcing and potential
explosion from battery gases. Never remove the
clamps while the unit is on.
Keep sparks ames or cigarettes away from
batteries.
Provide adequate ventilation to remove car exhaust.
In extremely cold temperatures, check for frozen electrolytic uid before connecting
the Clean Power System. Do not attempt to Charge a battery under 20°F. Allow the
battery to warm to room temperature before connecting the Clean Power System.
Never connect the clamps to more than one 12 volt battery at a time. Connection to 24
volts will dangerously overload the circuitry.
Do not expose the Clean Power System to rain or snow.
Warning! Never attach the Clean Power System to a battery that is connected to any
other tester or charging unit. Damage may result.
CAUSE OF BATTERY FAILURE
Incorrect Application: Wrong size battery may have inadequate cold cranking Amp
rating for original vehicle specications.
Incorrect Installation: Loose battery hold-downs cause excessive vibration, which
can result in damage to the plates.
Improper Maintenance: Low electrolytic uid and corrosion on battery connections,
can greatly reduce battery life and affect battery performance.
Age of Battery: If the date code on the battery indicates it is fairly old, the failure may
be due to natural causes.
Overcharging: Overcharging caused by a high voltage regulator setting or incorrect
battery charging can cause excessive gassing, heat and water loss.
Undercharging: Undercharging caused by a faulty charging system or low voltage
regulator setting can cause lead sulfate to gradually build up and crystallize on the
plates greatly reducing the battery’s capacity and ability to be recharge.
SAFETY
TROUBLE SHOOTING
Problem Possible Cause Reason/Solution
The unit is on, and
the voltage display
reads 0.0 Volts
The clamps are
not making a
good connection
at the battery.
Check for poor connections at
the battery. Clean connection.
Rock the clamp back and
forth so that the teeth on the
clamp jaw cuts through any
surface corrosion.
The connections
are reversed.
Unplug the unit and reverse
the connections. Check fuse.
The battery is
dead or defective.
Check the battery using a
battery tester.
The unit will not
start charging.
The battery
voltage is below
8 Volts causing
the unit not to
recognize the
battery.
Fully charge the battery using
a battery charger.
The unit is not
providing the
maximum rated
current.
The battery and/
or electrical
system is not
demanding the
maximum rated
current.
The unit is voltage limited
at the set voltage displayed
in the digital voltmeter. The
unit will provide up to the
maximum rated current to
keep the voltage at the set
point.
The cooling fan is
making noise.
The fan has build
up of dirt causing
it produce noise.
Blow dirt off of the fan blade
using compressed air.

VISUAL CHECK
Inspect Battery for terminal
corrosion, loose or broken
posts, cracks in the case,
loose hold-downs, low
electrolyte level, moisture,
and dirt around the
terminals.
Important Note: A damaged battery must be replaced before
proceeding.
Carefully perform the following before attempting any electrical
diagnosis.
INSPECTION
WHAT TO EXPECT
Auto Meter Clean Power System converts standard 120 VAC to a clean
regulated voltage DC power. The DC output voltage is adjustable from 13.0
to 14.8 V so that it can be set to most any manufacture’s specication for
ash reprogramming or battery charging. The voltage that is displayed on the
digital voltmeter is the voltage at the clamps / battery terminals. The Clean
Power System allows you to operate 12 VDC loads up to the unit’s rated
current output while maintaining at least 13.4 V. Please note that the voltage
displayed on the digital voltmeter will be lower than the power supplies
output voltage due to a small voltage drop in the leads.
The Clean Power Supply has the following protection features:
• Reverse battery polarity protection via replaceable fuses.
• Brownout input protection.
• Over current protection: cycle by cycle limiting as well as
rated current limiting.
• Over temperature protection.
VOLTAGE SETTINGS
Recommend Clean Power System Voltage Settings:
Flash Reprogramming: Follow the vehicle manufacture’s
recommendation. Typically range from 13.4 to 14.4 V.
Maintaining Battery State of Charge: Follow the battery manufacture’s
recommendation. Typical long term oat voltages range from 13.2 to 13.6
V at 68 F.
Vehicle Showroom Display / Demonstration: 13.2 V at 68 F.
Note: If the battery temperature reaches 125°F the charging rate must
be reduced or temporarily halted. This is done to avoid damaging
the battery.
